    摘要： A metallic separator according to a first embodiment is formed by obtaining a blank by rolling a metallic material having conductive inclusions, and removing a surface of the blank by 2% or more of the thickness of the blank. A metallic separator according to a second embodiment is formed by pressing a metallic plate so as to have a cross section including ridges and grooves alternatively, and removing parts of the ridged portions so as to make flattened surfaces. A metallic separator having conductive inclusions in its metal texture according to a third embodiment is formed by blasting a liquid containing two or more kinds of abrasives having different particle diameters to a blank after it has been rolled. A metallic separator having conductive inclusion in its metal texture according to a fourth embodiment is formed by blasting a passivation treatment liquid mixed with abrasives to the separator.

    摘要： A current-collecting structure in a fuel cell system includes conductive separators, current-collecting plates pressed toward the conductive separators, a plurality of good conductors dispersed between the conductive separators and the current-collecting plates and adapted to be deformed under the pressing to come into close contact with the conductive separators and the current-collecting plates, and a conductive binder. The conductive binder fills vacant spaces among the good conductors, the conductive separators and the current-collecting plates. The current-collecting structure in a fuel cell system provides a decreased contact resistance between the conductive separator and the current-collecting plate.

    摘要： In a fuel cell comprising a laminate wherein a membrane electrode assembly is held by separators, the separator (20A) has a projection (21) contacting an membrane electrode assembly (10) with the contact angle between this projection (21) and the membrane electrode assembly (10) is set smaller than the contact angle of water with respect to the surface of the separator (20A). Regardless of the surface property of the separator, a corner part formed between the separator projection and membrane electrode assembly which contact with each other is so structured that water is unlikely to remain or penetrate. Thus, the draining capability of the gas channel is enhanced, improving power generating performance.

    摘要： Disclosed is a fuel cell in which an electrolyte membrane-electrode structure is held between the first separator and a second separator. The electrolyte membrane-electrode structure comprises a solid polymer electrolyte membrane, a cathode-side electrode and an anode-side electrode. An end portion of the solid polymer electrolyte membrane projects outwardly beyond end portions of gas diffusion layers, and the both surfaces of the end portion of the solid polymer electrolyte membrane are held between the first protective film and a second protective film. The thickness of the first protective film is set to be thinner than the thickness of the second protective film.
